Fire sprinklers at a Los Angeles International Airport terminal switched on Sunday after a water pipe broke, dousing hundreds of people.
The terminal was temporarily evacuated, and the baggage claim and screening areas were slightly flooded, said airport spokesman Marshall Lowe.
The terminal was evacuated about 11:25 a.m., and at 11:55 a.m. passengers were allowed back in, officials said.
Long lines formed in front of the terminal as passengers were readmitted through security checkpoints.
Airport officials could not immediately give estimates on flight delays.
